TO ALL' WHOM IT llLlAYGONCERNeA Be it known that I', R. J'. GOULD; of vN ew York, 10 2 Liberty street, in the county andzState 4ci' N ew York, 'did invent a new and useful Improvement in Packing for Hose-Coupling, and otherv articles; and I do hereby declare that the following isn full, clear, and exactdcscriptionthereof, which willenable those skilled inthe 'art to make and use the Samb, reference being 'had to -the 'accompanying drawing, forming part of this specification,- in which"drawing-1l 1 Figure 1 representsalongitudinalcentral section of this invention. l Figure2 is a transverse section thereof, the plane of section being indicated by the line w, iig.\1, and: looking in the direction of'A arrow 1, marked opposite to that line. y l I Figure 3 isa similar section,"tsken in the plane indicated'by the line x, iig. 1, and looking in`the-direc tionofe'rrowij i' i` f I igure 4-is'a modification Vof my. packing-piece..

' This invention relates to a pecking fon chose-couplingor other article, which-consists of a. T-shaped strip or ring, of Indiarubber or otber--suitiblesoft-.end exible'matcriaht'be ends ot' the crossbar of which areilat v orly-shaped, and which is secured betwecnthe' surfacesto be joined, said surfaces being provided with 'square` or V-shsped recesses to-'correspnd to the'ends of the cross-bar of the pecking in'such a manner that when the `te be jcied"nre bl'lught` together, 'the' ends of the cross-bar' of theA packing are compressed by the v recesses, anda perfectly tightjointlis produced.'

'I will new proce'cd to deseribemy invention-in its application to chose-coupling, but it is obvious that the. saure packing-may be used for a' great many' dierent purposes. l

--A represents the' first, `and B the second half 4coupling'fvhich may be constructed in the form of an ordinary union joint, as shbwn in the drawing, to bo held together by a nut, -0,'01 which may be united -in any othcrL desirable manner. vThe joint between the endsof the twc half coup'lings'is rendered tight by n. packing-ring,

-a, which I makoby preference of Iudiarubber, but which might be made of leather or other suitable material. This packing-ringis T-shap'ed, and'it maybe firmly secured at one ond to the lirst half coupling A. If made of Indiarabbor, it-mny be attachcd'to said half coupling by vulcanizing it in the required position, or it may 'be fastened in anyother suitable manner, and if desired, the edge of the halt` coupling A may be made V-sha'pedA instead of making it -in the formshown in the drawing. Ono end ofthe cross-bnr of the packing-ringe is made V-shapcd, anda. correspdnding V-sbaped groove, b, Ais turned or therwi'seproduced inthe edge of the secod half coupling B, as elearly shown i'n figs. 1 and 3 ofthe drawing. When the two half couplings are brought together, the groove 6' overlaps 4the le'osc end of the packing-ring, and at the same time, bythe shape of'V laid groove, the packing is-iirmly crowdedjntcthe joint, and a' perfectly tight joint is the-result, which is not liable to become loaden-whatever the .lirectionot` the current of water passing thrcughthc coupling may be. If said 1 =ourrent^gaoves in the direction of the arrow markedin the `interior of the coupling in iig. 1, it meets the end of v thep'aeking-1ing, whiuh'is firmly -attached 'to theV halfeoupling A, and if the current moves in the opposite direction of said'rrow, it meetsv the edge of the packing-ring, which -is embedded in the V-shaped groove 6,'and

consequently said packing-ring is not liable to tip oi'cr,in whatever Adirection the current moves, and the joint renainfs tightunderjall circumstances and furthermore, if lthc joint is exposed. to an internal pressure, it will be'rendered tight bythe pressure itself, oven if thetwo half couplings should not be screwed up perfectly tight.. What I claim as new', and desire to secure by Letters Patent, is-

The arrangement lo t cfr-shaped packing-piece, a, having the "ends of the cross-bar flat or v-shapcd, in comi M bination with' corrcspondinglyyshaped recesses b in tho suifaces to .be joined, said packing overlapping the i ner surfaces ofbothv parte' A and B o f the coupling, substantially as und for the purposes set't'orth.
